Title: Semiconductor laser element
Inventor: OGAWA HIROSHI
IPC: H01S5/00
Filed: 1989-05-08
Abstract: PURPOSE:To realize single longitudinal mode oscillation without generating a transition region by forming two kinds of diffraction gratings in an element, with the same arrangement pitch period, and equalizing the respective average effective refractive indexes of guide layer material and diffraction grating material. CONSTITUTION:In an element, two kinds of diffraction gratings 37, 39 are formed with the same arrangement pitch period. A first diffraction grating 37 and a second guide layer 47 are constituted of material whose refractive index is no. A second diffraction grating 39 and a first guide layer 43 are constituted of material whose refractive index is n1. As a result, the average effective refractive index in the region where the first diffraction grating 37 is formed and the average effective refractive index in the region where the second diffraction grating 39 is formed become substantially equal. Hence a transition region is not formed, so that a semiconductor laser element capable of single longitudinal mode oscillation can be obtained.

Title: Preventing method for clogging of gas wiping nozzle
Inventor: HINOTO HAJIME
IPC: C23C2/18
Filed: 1978-09-19
Abstract: PURPOSE:To effectively prevent clogging of the wiping nozzle of the material which is hard to react and wet with the molten plating metal on steel hoops by wiping the steel hoops while maintaining said wiping nozzle at the temperature above the melting point of the molten plating metal. CONSTITUTION:While the foregoing wiping nozzle (e.g,; the nozzle comprising oxide film treating of the surface of aluminum, etc). is being maintained at the temperature above the melting point of the molten plating metal, wiping is accomplished with a non-oxidative gas or reducing gas. The heating methods of the wiping nozzle include the method of radiating from outside such as infrared ray lamp radiation or installing electric resistance wires to the inside or outside of the nozzle and heating them through electric resistance, etc. This wiping method does not cause clogging in the wiping nozzle even if the plate is passed at much higher speed than before and there is no need at all for any mechanical and artificial clogging removing works.
